Constructor Detail

Sampled_RepeatedHoldOutAssessParameterSet

public Sampled_RepeatedHoldOutAssessParameterSet()
                                          throws UnsupportedOperationException,
                                                 ParameterException

Constructs a new Sampled_RepeatedHoldOutAssessParameterSet with empty parameter values. This constructor should only be used to create "filled" Sampled_RepeatedHoldOutAssessParameterSets, i.e. to create Sampled_RepeatedHoldOutAssessParameterSets from a set of values and not to fill it from the platform user-interface.

Throws:

UnsupportedOperationException - if the Sampled_RepeatedHoldOutAssessParameterSet could not be constructed or the parameters could not be loaded

ParameterException - if the parameter for the percentages could not be created

Sampled_RepeatedHoldOutAssessParameterSet

public Sampled_RepeatedHoldOutAssessParameterSet(StringBuffer representation)
                                          throws NonParsableException

The standard constructor for the interface Storable. Constructs a Sampled_RepeatedHoldOutAssessParameterSet out of its XML representation.

Parameters:

representation - the XML representation as StringBuffer

Throws:

NonParsableException - if the Sampled_RepeatedHoldOutAssessParameterSet could not be reconstructed out of the XML representation (the StringBuffer representation could not be parsed)

Sampled_RepeatedHoldOutAssessParameterSet

public Sampled_RepeatedHoldOutAssessParameterSet(DataSet.PartitionMethod dataSplitMethod,
                                                 int elementLength,
                                                 boolean exceptionIfMPNotComputable,
                                                 int repeats,
                                                 int referenceClass,
                                                 double percentage,
                                                 boolean sameLength)
                                          throws ParameterException

Constructs a new Sampled_RepeatedHoldOutAssessParameterSet with given parameter values.

Parameters:

dataSplitMethod - defines the method used to split user supplied data into k mutually exclusive random-splits (available options are: DataSet.PartitionMethod.PARTITION_BY_NUMBER_OF_ELEMENTS and DataSet.PartitionMethod.PARTITION_BY_NUMBER_OF_SYMBOLS)

elementLength - defines the length of elements (sequences) the classifiers to be assessed are able to classify

exceptionIfMPNotComputable - a Sampled_RepeatedHoldOutAssessParameterSet is used in combination with an AbstractPerformanceMeasure-object to call assess( ... )-methods of Sampled_RepeatedHoldOutExperiments. If exceptionIfMPNotComputable==true an Exception is thrown in case of a user selected measure parameters that could not be computed.

repeats - the number of repeats of each iteration (mutually exclusive, randomly split data to obtain test and train data sets, train classifiers using train data sets and test them using test data sets) of that RepeatedHoldOutExperiment this Sampled_RepeatedHoldOutAssessParameterSet is used with

referenceClass - the index of the class for which the complete data set is used, typically this should be the smallest data set (to meet all constraints)

percentage - the percentage of the referenceClass data that should be used as test data in each iteration

sameLength - if true for test and train data set the sequences of the non-reference classes have the same length as the corresponding sequence of the reference class

Throws:

ParameterException - if the parameter for the percentages could not be created
